PostPosted: Mon 17 Nov 2008, 00:04    Post subject:  Zmixer and Alsamixer: no volume control (Solved)  

Running Pizza Pup 3.0.
Card: Intel ICH5 x
x Chip: C-Media Electronics CMI9739 x
x View: [Playback] Capture All x
x Item: Master

I am glad I at least have sound. My problem is I can't change the volume with either Zmixer or Alsamixer. In Zmixer, both Master and PCM are zero. Can't increase them. In Alsamixer, Master and PCM are zero and I can't even tab to them without Alsamixer locking up. Weird. I did manage to set the volume levels for Volume and PCM using the terminal and "setvol". My sound modules are as follows:

sh-3.00# lsmod | grep snd
snd_intel8x0 32684 0
snd_ac97_codec 90448 1 snd_intel8x0
snd_ac97_bus 2128 1 snd_ac97_codec
snd_pcm 77592 2 snd_intel8x0,snd_ac97_codec
snd_timer 23540 1 snd_pcm
snd 51396 4 snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer
soundcore 9408 1 snd
snd_page_alloc 10008 2 snd_intel8x0,snd_pcm
sh-3.00# cat/proc/asound
sh: cat/proc/asound: No such file or directory

This is from /tmp/bootsysinit.log:

/usr/sbin/alsactl: relocation error: /usr/sbin/alsactl: symbol snd_ctl_elem_add_integer, version ALSA_0.9 not defined in file libasound.so.2 with link time reference

This part of the log file shows up when I shutdown also.

I should note that I can control the volume when using XMMS and MPlayer. But having a tray app that I can use to mute sound would be more convenient when I answer the phone.

Any ideas on how to solve this?

Does Pizzapup not have a tray volume control? What window manager does it have? The best tray volume app, which used to be in Puppy (minivolume.tcl) uses setvol, but you can only use it with JWM or another window manager that can swallow programs.
For other window managers you could always try the absvolume from Puppy 4.x, or tray-mixer-0.1, which I posted to the forum the other day - I have no idea if they will work.

Pizza Pup uses Icewm and does not have a tray volume control. I just put a Zmixer shortcut on my desktop.

I may have a tray mixer that works in IceWM somewhere on my computer. I'll try to dig it up later this week or probably on the weekend. Not sure if it's still around.

You could make a script that toggles whether it's muted or not, and add a button on the tray for it. I don't remember if Pizzapup 3.0 had an entry on that toolbar-menu for editing it (not the main menu, the one over to the right of it's button). If not, the files are in /root/.icewm/. I forgot what it's name is. I've been using JWM since summer, because I haven't gotten around to installing IceWM again yet, and JWM isn't as annoying now as the older versions were.


As for why it isn't working, I haven't the foggiest idea. Did you try the alsa wizard? Should be something like Start->Setup, but I don't remember if that was still the location back then.

For anybody who is not already aware, Pizzapup 3.0 was based on Puppy 2.12.

Do any other versions of Puppy work properly? If version 2.14 works, you could switch to Pizzapup 3.0.1, which was based on that. I think I did a sloppier job on that than on 3.0 though. I let myself get rushed near the end. I was going to make a 3.0.2 but never had time.

Code:
sh-3.00# cat/proc/asound
sh: cat/proc/asound: No such file or directory
FWIW, you made a typo. The space between 'cat' and '/' is missing.

Hey Pizzasgood,

Nice to finally meet you. First, let me say that your puplet is the one I always pass out to Windows users interested in Linux. Relatively small but still fully featured. Having Mplayer (w/ codecs) able to play most videos and Xmms is a big attraction.
As for my volume control problem, I forgot to include the fact that I've tried at least 10-15 other Puppies and they don't work properly either. Alsa wizard finds my sound card OK. I should add that other Linux distros (DSL) don't work either.
This is a problem I've lived with for quite a while now. I've also done alot of research here in the forum and on Google. Nada! That's why I'm throwing it out there for help. Yeah, I still have audio, so it could be alot worse. Somehow, I don't think that having a tray app is the issue. As a matter of fact, When trying the newer Pups with JWM, when I use the vol tray app it'll just disappear! Like I removed it or something. Weird.

Both the absvolume in Puppy 4.x and the tray-mixer-0.1 that I posted will work with Icewm as they run in the system tray like glipper.
I was pretty sure icewm actually had its own tray volume control though.

Not in the version I used, AFAIK. That was about two years ago, and the specific IceWM package may have been older yet. So that may be a newer development. Or it may just be a third-party deal, that people have just been putting into their IceWM packages.


@Yogi: What about amixer?
Code:
# amixer sget PCM
Simple mixer control 'PCM',0
  Capabilities: pvolume
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 255
  Mono:
  Front Left: Playback 255 [100%] [0.00dB]
  Front Right: Playback 255 [100%] [0.00dB]
# amixer sset PCM 00
Simple mixer control 'PCM',0
  Capabilities: pvolume
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 255
  Mono:
  Front Left: Playback 0 [0%] [-51.00dB]
  Front Right: Playback 0 [0%] [-51.00dB]
# amixer sget PCM
Simple mixer control 'PCM',0
  Capabilities: pvolume
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 255
  Mono:
  Front Left: Playback 0 [0%] [-51.00dB]
  Front Right: Playback 0 [0%] [-51.00dB]

I suspect that that won't work either. It seems like all things alsa are defective for you.

Setvol is not alsa. I don't know what exactly it is, but it doesn't touch alsa at all. At lease not directly. That slider I mentioned above that works in IceWM is something I cobbled together two years ago, and when I did the actual volume setting stuff I decided to just grab the source for setvol and copy the functions out of it that dealt with volume. I don't have the source from setvol around anymore (probably is on the puptrix server though), but when looking for it I did uncover my old slider, complete with source. It makes no mention of alsa anywhere. It interacts with the volume through /dev/mixer and apparently uses the header linux/soundcard.h for this.

So, I dusted it off, made some minor tweaks so that it should hopefully compile on any Puppy since 2.00 (maybe earlier), and packaged up the source for you. Inside are just a couple source files and a script called 'compile-it'. Assuming you have devx_xxx.sfs installed (in your case, devx_212.sfs, renamed or symlinked to devx_300.sfs), you can simply click or otherwise execute that script and it should compile. (I cobbled this thing together before I knew how to make 'makefiles').

That should create an executable file named 'eggtray-volume'. Running it should probably put an icon into your task-bar, but I don't know if you have icewmtray running by default in Pizzapup. You may need to launch that by hand (just run icewmtray and I think it will start up). The eggtray-volume program puts a speaker icon in the taskbar, which upon clicking brings up a window with a slider in it, that may or may not work. Since setvol works, I imagine it will.

If it does work, you can copy the binary to /usr/local/bin and then modify a script to load it automatically. Depending on what IceWM package I used, there may or may not be a script called /root/.icewm/startup that you could add it to (along with icewmtray if needed). Otherwise you could put them into /root/.xinitrc near the end but before the 'exec $CURRENTWM'.

I warn you, I threw this together two years ago when I knew nothing at all about GTK programming, so the interface is dirt. You have to click the 'x' to close the window. Clicking the icon a second time just opens a second window. There is not auto-mute option.


If it works for you, I would be willing to fiddle with it the next time I get some free time to smooth out the interface, so that you can right-click or something to mute without opening the window, and so the window itself isn't so stupid. I don't know a lot more about GTK now, but I know enough to make something that isn't basically a copy-paste from a couple tutorials, which is what the interface of this currently is.


By the way, this also works fine in 4.11 with JWM. So if you want to use a newer Puppy and that one's stuff doesn't work, you could resort to this.

Hi Pizzasgood,

First, these results:

sh-3.00# amixer sget PCM
Simple mixer control 'PCM',0
Capabilities: pswitch pswitch-joined
Playback channels: Mono
Mono: Playback [on]

sh-3.00# amixer sset PCM 00
Simple mixer control 'PCM',0
Capabilities: pswitch pswitch-joined
Playback channels: Mono
Mono: Playback [on]

Yeah, I too think Alsamixer is adversely affected in some strange way I don't understand. But I do know that 'setvol' (PCM only) has an on/off affect on my sound. If I set PCM to "0" (no audio) then I have no sound. But if I set PCM to any value from 1 - 100 it's the same sound volume. Basically, it's either 'on' or 'off'.
Again, what do you think about this:

This is from /tmp/bootsysinit.log:

/usr/sbin/alsactl: relocation error: /usr/sbin/alsactl: symbol snd_ctl_elem_add_integer, version ALSA_0.9 not defined in file libasound.so.2 with link time reference

What is this 'alsactl: relocation error' all about? It sounds like it could be causing this problem. Don't you think?

I don't know. I wonder what % of Linux users out there are also having sound issues. Is it because ALSA can't keep up with the various/many sound cards and chips on the market? I think if Linux is to become more mainstream this has to be a non-issue for entry users.

I think that means that alsactl is trying to use a function or structure from the libasound.so.2 library, but doesn't see it (the function, not the library). As for what that means, not sure. Possibly incompatible versions. Maybe try installing devx_xxx.sfs, tracking down the source for libasound, and recompiling it. I did some googling and it looked like some other people had a similar problem that was resolved by updating the libasound package.

Some other things that googling suggested were requiring extra options in the 'alias snd-card-0 snd-intel8x0' lines, and removing any extra instances of alsactl from /bin and /sbin (doubt that's the problem).

I think the three most likely problems are a bad libasound library, a wrongly configured driver, or a bad driver.

But I really don't know that much about the sound system, so I can't help much more than this. I know absolutely nothing about configuring drivers. Sorry. Sad

Hopefully somebody else here with more knowledge of soundcards can help.



Otherwise as a last resort to at least grant yourself some control, you could get an amp and stick that between the computer and the speakers, so that you can manually change the volume (assuming they aren't the type with a volume knob in them already). Yeah, not nearly as good as fixing the problem, but it lets you turn things down at least.

recompile libasound, alsa-driver, alsa-lib and alsa-utils -all with a version which matches properly with the kernel version you are using -oops, the developer was suppsoed to do that....

Subject description: Solved (cheated)
 

Decided to use an old A-Open AW850 Cobra pci sound card I found stashed in my closet. It uses the C-Media CMI8738 audio chip (which is supported by OSS and ALSA). See here - http://www.linuxquestions.org/hcl/index.php/cat/23.
I now have volume control with Zmixer. Yeah, I took the easy way out but if you knew the (Linux) hardware compatibility of your future purchase why make it hard on yourself. I guarantee you alot of users here will do their homework next time before they buy. Towards that end, I offer the following sites to get you started in that direction.

Linux Soundcard Drivers: A brief guide for users and developers (a little dated but still a good read) - http://www.linuxdevcenter.com/pub/a/linux/2001/05/17/drivers_1-intro.html

ALSA SoundCard Matrix - http://bugtrack.alsa-project.org/main/index.php/Matrix:Main

Linux on Laptops - http://www.linux-laptop.net/

Even though this Cobra card works in Pizza Pup all I get is basic stereo. But that's OK cause all I have is a two-channel w/sub-woofer speaker system. There are Linux drivers on the cd If I want to re-compile Puppy, which does not appeal to me. For those of you with desktops you might want to research using a compatible pci sound card. This card I'm using is about six years old. I have found Ebay a potential source for an inexpensive solution. Those of you with laptops that are mute I'm not sure there is an easy solution.
